I am sorry if you think a question on how Capital One would know about the husband if they weren't on the account was "defending" the bank.
But seriously since they did respond. Yes the default feeling of some is that the banks are evil and will do anything they can to get their money. Some people would go as far as thinking that bank employees are personally targeting them for one reason or another. The OP really wants to believe that Capital One is so concerned about loosing money on that account, that they gave her "personal" attention. In that Capital One is willing to possibly commit a crime in obtaining the Husbands(and how would they know 100% that he was the husband) information. Then on top of that INTENTIONALLY posting invalid information on the husbands credit reports. Which at the very least is a violation of the Fair Credit Reporting Act where they could be sued. All because they "think" that the OP will become delinquent. Then even if they "stick" the husband with the account and the wife is delinquent wouldn't that pretty much reduce the possibility that the husband would pay either.
Yes, let the conspiracy theories fly.
Really..banks are not that concerned if you are delinquent. Not that they don't want their money..because they do. But if you don't pay they will just sell your account(at a discount) to a Collection Agency. To them that is a much more effective way to cut their losses than the "lets put the account on the spouse who may not pay us either", because at least they get something.
Not knowing the exact details it is hard to say if the Husband was not a co-signer and the OP may be trying to use some technicallity(right or wrong) to keep the husband from being responsible. But if the loan was to the OP's name ONLY, and there was not a single reference to her husband on the terms or the check then yes the OP is most likely right it should not be on the husbands report. And if they refuse to remove it then he(since it is on his report) may want to look into going after them for violations of the Fair Credit Reporting Act. But one caviat to that is that if this was a Community Property State situation that may change things, although New Jersey is not one.
